Background
With the continuous improvement of living standard, the quality requirements of people on underwear are increased, and the underwear with various functions, such as antibiosis, radiation protection, warm keeping and the like, are produced. In hot summer, people urgently need a close-fitting garment with a cooling effect, wear a cool and breathable garment in high-temperature weather, can greatly improve the comfort level of a human body, and is favorable for work and life.
At present, jade fibers are generally added into a fabric to prepare the fabric with a cooling function, for example, a jade fiber blended fabric disclosed in Chinese patent literature, the publication No. CN105544051A of which is woven by warp yarns and weft yarns, wherein the warp yarns are formed by blending jade fibers and hemp fibers, the jade fibers account for 45-60% by weight, and the hemp fibers account for 40-55% by weight; the weft yarn is formed by blending jade fibers and mint fibers, wherein the jade fibers account for 38-64% by weight, and the mint fibers account for 36-62% by weight.
However, in the prior art, the ice-cool fabric made of jade fibers has single functionality, and is difficult to meet the increasing functional requirements of people on underwear.
Disclosure of Invention
The invention aims to solve the problems that the ice refreshing fabric made of jade fibers in the prior art has single functionality and is difficult to meet the increasing functional requirements of people on underwear, and provides a jade zinc ice refreshing health-care fabric and a preparation method thereof.
In order to achieve the purpose, the invention adopts the following technical scheme:
the jade zinc cool health care fabric is formed by weaving warps and wefts, wherein the warps and the wefts are formed by blending jade zinc fibers and cotton fibers; functional powder is loaded in the zinc jade fiber, and the functional powder comprises jade powder, tourmaline powder and nano zinc oxide; the fabric is loaded with a coating comprising aromatic slow-release particles, the aromatic slow-release particles have a three-layer core-shell structure, and the aromatic slow-release particles sequentially comprise a mesoporous silica inner core loaded with plant essential oil, a phase change material layer consisting of hexadecanoic acid and tetradecanol and an amorphous silica protective layer outside the phase change layer from inside to outside.
The fabric is formed by blending and weaving jade zinc fibers and cotton fibers loaded with jade powder, tourmaline powder and nano zinc oxide. The cotton fiber has good hygroscopicity and skin-friendly property, and can improve the wearing comfort of the fabric; in the jade zinc fiber, jade is a good thermal conductor, so that the fabric made of the jade zinc fiber added with jade powder can make human bodies have good cooling feeling, and is particularly suitable for wearing in hot summer or sports; moreover, the jade contains abundant mineral substances and trace elements which are beneficial to the human body, and the jade is attached to the skin of the human body for a long time and released, so that the blood microcirculation can be improved, the metabolism is promoted, and the effects of preventing diseases and eliminating fatigue are achieved. Tourmaline can automatically and permanently release negative oxygen ions, is a natural negative ion generator, and jade zinc fiber loaded with tourmaline powder is added into the fabric, so that the fabric can release negative ions, and when the underwear is made, the underwear can purify blood, revive cells, improve immunity of human body, and is helpful for improving headache, insomnia, neurasthenia and other phenomena. The nano zinc oxide in the zinc jade fiber also has good heat-conducting property, and is favorable for heat dissipation to form cool touch when added into the fabric; and the nano zinc oxide has good infrared ray and ultraviolet radiation resistance and sterilization functions, so that the fabric has radiation protection and antibacterial effects, and the wearing health of underwear is met.
In order to enable the fabric to release fragrance for a long time and have the effects of relieving pressure, pleasuring mood, sterilizing and deodorizing, the invention also loads the fragrance sustained-release particles on the fabric. The aromatic slow-release particles have a three-layer core-shell structure, and sequentially comprise a mesoporous silica core loaded with plant essential oil, a phase change material layer consisting of hexadecanoic acid and tetradecanol and an amorphous silica protective layer outside the phase change layer from inside to outside. The mesoporous silicon dioxide of the inner core is used for adsorbing and loading the plant essential oil in the pore channel of the mesoporous silicon dioxide, so that the primary slow release of the volatile plant essential oil is realized, and the fragrance release time of the fiber is prolonged; the amorphous silicon dioxide layer on the outer layer plays a role in shaping and protecting the phase-change material layer; the intermediate phase change material layer is used for realizing the controlled release of the plant essential oil at different temperatures: the phase change temperature of the phase change material layer formed by mixing hexadecanoic acid and tetradecanol is about 32 ℃, after the aromatic slow-release particles are made into underwear along with fibers, when the underwear is worn and contacted with a human body, the temperature is increased, the phase change material layer in the middle of the aromatic slow-release particles is changed into a liquid state, the compactness of the shell layer is reduced, the release rate of the plant essential oil loaded in the core is accelerated, and the fragrance release amount is increased; when the clothes leave the human body, the temperature is reduced, the phase change material layer is solidified into a solid state, the compactness of the shell layer is increased, the release amount of the plant essential oil loaded in the inner core is reduced, and the fragrance is weakened.
Therefore, the jade zinc ice health care fabric has the health care effects of ice, anion release, antibiosis and the like, and can release fragrance by volatilizing the plant essential oil when being worn, so that the functions of sterilization, deodorization, pleasant mood and the like are achieved. And the release of the fragrance can be controlled through the temperature, so that the fragrance is released more when the clothes are worn and less when the clothes are not worn, the loss of the plant essential oil is effectively reduced, and the fragrance release time of the fiber is prolonged. The fabric can be used for preparing various close-fitting clothes such as underwear, body shaping clothes, sports underwear, socks, pajamas, T-shirts, shirts and the like, and is beneficial to the comfort and health of human bodies.
Preferably, the preparation method of the aromatic sustained-release particles comprises the following steps:

The invention utilizes a sol-gel method and takes 4-azidoaniline hydrochloride as a pore-forming agent to prepare mesoporous silicon dioxide. Because the surface of the silica gel formed by hydrolyzing tetraethoxysilane under the catalysis of alkali is negatively charged, the method utilizes the electrostatic attraction effect between the quaternary ammonium salt group with positive charge in the pore-forming agent 4-azidoaniline hydrochloride and the silica gel with negative charge to lead the pore-forming agent to be adsorbed and enriched in the silica gel, then leads the phenyl azide group in the pore-forming agent to be decomposed into nitrogen to escape through the irradiation of ultraviolet light, thereby initially forming a pore channel in the silica gel, and finally leads other organic groups in the pore-forming agent to be decomposed through high-temperature sintering, and further expands pore channels to obtain the mesoporous silica carrier with larger specific surface area and good load performance.
